HEATING APPARATUS.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed December 26, 1917. Serial No. 208,834.

' New York, county and State of New York,

have invented certain new and useful Improvements in Heating Apparatus, of which a the following is a speclfication.

The invention relates to heating apparatus and particularly to a device or attachment which is appliedto or used in conjunction with a radiator. The device or attachment is particularly useful when applied to a radiator that is part of a heating system, such as a steam or hot waterradiator employed, for example, in dwelling houses, oflice buildings and apartments. I

As illustrating a specificembodiment of the invention reference is made to the accompanying drawing forming a part ofthis specification and in whichdrawing,

Figure 1 is a side view of a radiator with the devic or attachment applied thereto.

Fig. 2 is an end view of a radiator showing the device or attachment in position relative to the radiator.

Fig. 3 is a plan View showing a form of heating coil that constitutes a part of the device or attachment.

Fig. 4 is a vertical view substantially hollow in cross-section showing some of the fittings and piping employed in the device or attachment. Y a

The radiator is designated by 1. It is ordinarily supplied with the heating medium, as for example steam, through valve controlled supply piping 2. This piping includes the ordinary radiator valve or hand stop valve 3. As is wellknown, when said valve controlled supply piping 2 is closed no heating medium is being supplied to the radiator.

The radiator is shown as having associated therewith an attachment A which may, be considered as connected to the lower far end of the radiator since it is connected to the lower part of the radiator and to theend which is farthest from, the place where the heating medium is usually supplied. In many radiators, at this place there is provided a screw-plug vwhich seals said lower far end of the radiator.

According to the present invention, in place of the plug usually employed there is inserted at the lower far end of the radiator The other end of said heating a special screw-plug or. fitting 4. If by chance the radiator is not provided with a threaded opening at this place then the device or attachment may be applied asby boring a hole in the radiator, threading and then inserting the shaped screw-plug 4 in an obvious manner; or, if the radiator is a double pipe system it may be connected in the piping betweena radiator valve and the radiator. This special screw-plug or fitting 4 has a longitudinally extending upper conduit 'or passageway 5'and a lower conduit or passageway 6 which may be referred to as the inlet and outlet passageways respectively. The special screw-plug 4 is hollow and the inner 'or radiator end thereof is threaded on the exterior where it enters the threaded opening in the radiator. The plug is threaded as at 7 and receives therein a bent pipe or inwardly and upwardly extending directing tube 8,the-function of which tube is to direct incoming hot water or steam into i the upper portion of the base of the radiator whereby a proper circulation will be set up in the radiator when the device or attachment is employed, as will hereinafter appear. The special screw-plug 4 is also threaded, as at 9, and receives therein the horizontally extending connecting tube 10. This tube 10 is connected to the T or fitting 11 into which T there is screwed a valve controlled cup-n1ember 12 that serves as a means for permitting the insertion of the circulating water, when desired. The lower part of the special screw-plug 4 is threaded, as at 13, and receives the upper end of a vertically extending or depending pipe 14. The lower end of said pipe 14,is connected to an elbow 15 at one end of a heating coil 16 and leads from the lower hollow interior portion of the plug or special fitting to the heating coil.

coil has an elbow 17 connected to the T 11 by the substantially vertically extending or upstanding piping which includes the members 18, 19 and 20 and which leads from the heating coil to the upper passageway in the special fitting. The heating coil 16 is preferably heated by means of a gas burner B which is supplied with gas, as through piping 21, controlled by hand valve 22. If desired other means could be employed for heating the It is well known that when radiators are closed, for example steam radiators where there is only a single piping both for feedin steam to the radiator and for conducting steam therefrom, more or less water of condensation will collect in the lower portion of the radiator. If the radiator valve or hand stop valve 3 is closed, it may be that in many instances enough water of condensation will collect in the bottom of the radiator to provide the required circulating water when the device or attachment is in use, in which case further water will not be added prior to employing the device or attachment in -performing its desired function. Whether or not there is sufficient water within the radiator is readily determined, as by opening the hand valve 24, and if there is notthe desired amount of water then it can be supplied through the cup-shaped member 12 the valve 24; of which is now open. When the desired amount of water is in the radiator the valve 24; is closedif not already clos dazhe stop valve 3 still remains closed, and the device or attachment is-ready to be operated. This is accomplished by opening the valve 22 of the gas supply and lighting the burner B. y

As the water in the coil heats it is caused to circulate in the direction indicated by the arrows, that is the hot Water passes from the coil 16 through elbow 17, members 18, 19, 20, T or fitting 11, tube 10, upper inlet passageway 5 and directing tube 8 through the radiator. The cooler water flows from the radiator through the lo-wer outlet passageway 6, pipe 141 and elbow 15 into the heating coil where it is heated and again caused to be circulated. w I p The device or atta'chmentis applicable to a radiator which is connected in what i's'ordi na'rily known as the double piping system and it is also applicable to a radiator where the heat for the radiator is to be supplied solely by the employment of the device or attachment.

The device or attachment is particularly applicable to a radiator located in a room where the ordinary supply of heat thereto is interrupted or cut off, as for example by the early'banki'ng of a furnace, or due to the usual supply being temporarily out of commission. The device is applicable not only to a radiator used a steam heating system but also to a radiator employed as a part of a water heating system.

It will also be noted'that the device or attachment is constructed so that the heating coil, which may be broadly considered as a 1 water chamber member, the gas burner andvation than the fitting or plug, as is manitest from an inspection of Fig. 1 p

The radiator may have any suitable air or vent valve as V, and if desired this valve V can be embodied in the form of a safety valve construction to permit of the escape of 6X1 cess pressure, Wlli'lflSllGd.

he improvements herein set forth are not limited to the precise construction and arrangement shown and described for they may be embodied in various forms and modifica tions without departing from the spirit and scope of the invention.

What I claim is:

An attachment to be applied to the far end of a radiator for supplying auxiliary heat to said radiator, comprising a plug adapted to be screwed into the aforesaid end of the radiator, said plug having a horizontally disposed conduit therein communicating with the interior of the'radiator, a pipe threaded into the underside of the said plug and in constant communication with the said conduit, a horizontally disposed heating coil extending beneath the radiator and having one end connected to s aidpipe, a hood incloslng said heating coil, an upwardly extending pipe screwedinto the plug above the horizontally disposed conduit in said plug, the'other end of said pipe passing to the interior of the radiator, a horizontally disposed pipe threaded into the plug at thesid e opposite the said upwardly extendinopipe, the two pipes being in alinement anc communicating with each other through a conduit in the plug above the first named conduit, connecting means extending between the last named horizontal pipe and the heating coil, and a valve controlled conduit communicating with both the heating coil and the radiator. v
